Allstarlink 2 separate nodes that wont connect to each other

Each node is on its own raspberry Pi running HamVoip
My 1st node is UHF, all works as it should. Using ports 4569 & 5038
Port 4569 shows OPEN when I check it on canyouseeme.org

My 2nd node is VHF. All seems to be working. Using ports 4570 & 6038
Port 4570 shows CLOSED when I check it on canyouseeme.org

Both 4569 & 4570 are port forwarded to their respective PI's IP address.

I can connect my 2nd node to other Allstar nodes and it works fine.

When I try to connect my 1st node to my 2nd node, my supermon screen shows it "Connecting" for 5 seconds then disappears"
